Garmin's GI-106A GPS/VOR/LOC/Glideslope Indicator is the indicator designed to work with the Garmin GNS-430 / GNS-430W, GNS-530 / GNS-530W, GNS-480 / CNX-80, and other GPS units.

Like the King KI-206 / KNI-520 or Collins IND-351 / IND-351A, the GI-106A has rectilinear meter movements, instead of pendulum, which makes it easier to read. This is especially nice when flying an ILS, since the needles stay perpendicular to each other. This feature helps the pilot to better determine the degree of correction needed to follow the approach accurately.

An uncommon GI-106A feature is a built-in Nav Source annunciator. This shows green when used with a GPS source, and white when used with a VOR or Localizer source. While this annunciator is not generally sufficient on its own to allow an installation to earn an IFR approval, it is definitely a handy backup.

This indicator does not contain a VOR/LOC Converter, which permits its use with a GPS. The GI-106A and an Annunciator Control Unit (ACU), if required for your GPS, can be used to meet the FAA requirements for an IFR GPS installation.

The GI-106A also features:

Non-reflective lens

Internal lighting

Since the Garmin GI-106A does not contain an internal VOR/LOC Converter, it is designed to be used with NAV equipment that does include this converter, such as:
